Im trying to remove the Accessories mod mid-save, i have Curios installed on version 5.11.0 for 1.20.1 and i made sure i was using cclayer mod previously - but it keeps crashing because of the items in my inventory.. (already tested it, and it wasn't just one item in particular but multiple different seemingly random ones from various different mods causing the same crash over and over)

Error im facing:

Description: Exception in server tick loop
java.lang.IllegalArgumentException: Expected UUID-Tag to be of type INT[], but found LIST.

Is there any way to do this?

Here is the full crash log:

crash-2025-01-10_20.13.55-server.txt

It's not advised to remove Accessories afterward, but I believe this might be due to issues with reading and writing items that was patched for 1.20.1 and fixed in 1.21 and up.

So there is nothing i can do effectively?

Not really for 1.20.1 besides making a mod to fix the issues with the data or just manually edit the NBT of the item to properly adjust the data from a NBT list to a NBT INT[]
